Description

Die Erfindung geht von einer Einrichtung zum Empfang von Verkehrsmeldungen gemäß dem Oberbegriff des unabhängigen Patentanspruchs aus.The invention is based on a device for receiving traffic reports according to the preamble of the independent claim.

Einrichtungen zum Empfang von Verkehrsmeldungen sind beispielsweise in Form von Autoradiogeräten, darüber hinaus in Form von Fahrzeugnavigationssystemen bekannt, die über einen Empfänger für Rundfunksignale und einen Dekoder zur Auswertung in den Rundfunksignalen enthaltener Verkehrsmeldungen verfügen. Solche Verkehrsmeldungen werden beispielsweise mittels des sogenannten Radio Daten Systems (RDS), wie beispielsweise in der Europäischen Norm EN 50 067 spezifiziert, in Form von TMC-(traffic message channel)- Verkehrsmeldungen, wie in den internationalen Normen ISO 14819-1, -2, -3 spezifiziert, von den Rundfunkanstalten im Sendegebiet der Bundesrepublik Deutschland ausgestrahlt.Devices for receiving traffic reports are known, for example, in the form of car radio devices, moreover in the form of vehicle navigation systems, which have a receiver for broadcast signals and a decoder for the evaluation of traffic reports contained in the broadcast signals. Such traffic announcements are specified for example by means of the so-called Radio Data System (RDS), as for example specified in European Standard EN 50 067, in the form of traffic message channel (TMC) traffic reports, as in International Standards ISO 14819-1, -2 , -3 specified, broadcast by broadcasters in the broadcasting area of the Federal Republic of Germany.

Die empfangenen Verkehrsmeldungen können in einem Fahrzeugnavigationssystem zur Realisierung einer sogenannten dynamisierten Zielführung, d.h. zur Berechnung einer Fahrtroute unter Berücksichtigung von durch die Verkehrsmeldungen repräsentierten Verkehrsstörungen, verwendet werden. Dazu werden die Durchfahrwiderstände der von den gemeldeten Verkehrsstörungen betroffenen Streckenabschnitte in der für die Routenberechnung verwandten digitalen Karte beeinflusst, insbesondere erhöht.The received traffic reports can be used in a vehicle navigation system for the realization of a so-called dynamic route guidance, ie for the calculation of a route in consideration of traffic disturbances represented by the traffic reports. For this purpose, the transit resistances of the sections affected by the reported traffic disturbances are influenced, in particular increased, in the digital map used for the route calculation.

Es sind ferner Einrichtungen zum Empfang von Verkehrsmeldungen bekannt, die über eine Mobilfunk-Verbindung einen vorgegebenen Dienstanbieter kontaktieren und von diesem zur Verfügung gestellte Verkehrsmeldungen, die ebenfalls dem TMC-Standard genügen können, abrufen. Üblicherweise sind die vom Dienstanbieter zur Verfügung gestellten Verkehrsinformationen auf den Staat beschränkt, in dem er seinen Sitz hat. Beispielsweise stellt ein über eine deutsche Telefonnummer erreichbarer Dienstanbieter regelmäßig nur Verkehrsinformationen zur Verfügung, die das deutsche Verkehrswegenetz betreffen, nicht jedoch solche für das unmittelbar angrenzende Ausland.There are also known devices for receiving traffic reports, which contact a given service provider via a mobile radio connection and retrieve traffic information provided by the latter, which can likewise satisfy the TMC standard. Usually, the traffic information provided by the service provider is limited to the state in which he has his seat. For example, a service provider that can be reached via a German telephone number regularly only provides traffic information concerning the German traffic route network, but not those for the directly adjacent foreign countries.

Da sich die Verkehrsmeldungen mit der Zeit ändern, erfolgen solche Anrufe der mobilen Empfangseinrichtung beim Dienstanbieter regelmäßig in vorgegebenen zeitlichen Abständen. Die Anrufe beim Dienstanbieter, ferner aber auch die Übertragung der Verkehrsmeldungen vom Anbieter zum Empfänger über die bestehende Mobilfunkverbindung verursachen Kosten, ferner werden die Verkehrsmeldungen üblicherweise nur gegen eine Gebühr zur Verfügung gestellt.Since the traffic messages change over time, such calls of the mobile receiving device at the service provider are made regularly at predetermined intervals. The calls to the service provider, but also the transmission of traffic information from the provider to the receiver over the existing mobile phone connection cause costs, furthermore, the traffic reports are usually made available only for a fee.

Verlassen solche bei einem Dienstanbieter Verkehrsmeldungen abfragende Empfangseinrichtungen den Staat des Dienstanbieters, fragt die Empfangseinrichtung nichts desto trotz weiterhin Verkehrsinformationen bei demselben Dienstanbieter ab. Die daraufhin vom Dienstanbieter an den Empfänger übertragenen Verkehrsmeldungen sind für dessen, nun ausländischen Standort regelmäßig von untergeordnetem Interesse, insbesondere enthalten sie keine Informationen, die seinen aktuellen ausländischen Standort betreffen. Erschwerend kommt hinzu, dass einem Nutzer des Verkehrsmeldungsempfängers das Fehlen für den aktuellen Standort relevanter Verkehrsmeldungen möglicherweise nicht auffällt, denn es ist ja durchaus möglich, dass im Bereich seines Standorts keine Verkehrsstörungen vorliegen. Neben den Verbindungskosten für die Mobilfunkanrufe und den Service-Gebühren für die abgerufenen Verkehrsinformationen fallen hier zusätzlich Gebühren für die Nutzung des Mobilfunkgeräts im Ausland an, ohne dass die erhaltenen Informationen für den Empfänger einen Nutzen haben.If such receiving devices requesting traffic information from a service provider abandon the state of the service provider, the receiving device nonetheless continues to request traffic information from the same service provider. The traffic messages subsequently transmitted by the service provider to the receiver are regularly of secondary interest for the foreign location, in particular, they do not contain any information concerning its current foreign location. To make matters worse, a user of the traffic message receiver may not notice the lack of relevant traffic reports for the current location, because it is quite possible that there are no traffic disruptions in the area of his location. In addition to the connection costs for the mobile calls and the service fees for the retrieved traffic information fall here in addition charges for the use of the mobile device abroad, without the information obtained for the recipient have a benefit.

Die WO-A-98 15075 offenbart ein Verkehrstelematikgerät, bei dem ein Autoradio-Modul, ein RDS-Modul, ein GSM-Funktelefon-Modul und ein Ortungs- und Navigationssystem in einem Gehäuse angeordnet sind. Mit Hilfe des Telematikgeräts können Informationen sowohl mittels des Autoradios, als auch über das GSM-Funktelefon empfangen werden. Bei den mittels des Autoradios empfangenen Informationen handelt es sich beispielsweise um RDS-TMC-Verkehrsmeldungen. Das Funktelefon-Modul ermöglicht das Absetzen von Notrufen beispielsweise bei Fahrzeugpannen, wobei eine aktuelle Fahrzeugposition mit übertragen wird. Ferner kann über das Funktelefon-Modul auch eine Routenanfrage an eine Zentrale getätigt werden sowie eine Übermittlung einer zu dieser Anfrage berechneten Route von der Zentrale an das Telematikgerät im Fahrzeug erfolgen. Auf Basis dieser Route kann eine Zielführung durch die Navigationskomponente erfolgen. Bei der Routenberechnung können die o.g. TMC-Verkehrsmeldungen, die auch in der Zentrale bekannt sind, berücksichtigt werden.WO-A-98 15075 discloses a traffic telematics device in which a car radio module, an RDS module, a GSM radio telephone module and a positioning and navigation system are arranged in a housing. With the help of the telematics device information can be received both by the car radio, as well as via the GSM radio telephone. In the received by the car radio Information is, for example, RDS-TMC traffic reports. The radiotelephone module allows the discontinuation of emergency calls, for example, in vehicle breakdown, with an up-to-date vehicle position is transmitted. Furthermore, via the radio telephone module, a route request can also be made to a central office and a transmission of a route calculated for this request from the central office to the telematics device in the vehicle can take place. Based on this route, route guidance can be carried out by the navigation component. In the route calculation, the above-mentioned TMC traffic reports, which are also known in the control center, can be taken into account.

Die DE-A-100 39 663 offenbart ein System zur Wiedergabe von Informationen betreffend ein oder mehrere Objekte in Abhängigkeit eines Benutzerstandorts, wobei die Informationen in einer Mehrzahl von Informationsquellen bereit gestellt sind. Anhand der mit einer Positionsbestimmungseinrichtung ermittelten geografischen Position und abhängig von Auswahlkriterien wird auf einen Speicher zugegriffen, in dem Informationen zu dem entsprechenden Objekt abgelegt sind. Der Speicher kann als interner Speicher ausgeführt sein, daneben können die Informationen auch über ein Rundfunkprogramm oder eine Intemetadresse abgerufen werden, wozu im System eine Liste vorliegt, in welcher die entsprechenden Quellen und die zugehörigen Zugriffsadressen gespeichert sind.DE-A-100 39 663 discloses a system for reproducing information relating to one or more objects depending on a user's location, the information being provided in a plurality of information sources. Based on the determined with a position determining device geographical position and depending on selection criteria is accessed to a memory in which information about the corresponding object are stored. The memory can be designed as internal memory, in addition, the information can also be retrieved via a broadcast program or an Internet address, for which there is a list in the system, in which the corresponding sources and the associated access addresses are stored.

Vorteile der ErfindungAdvantages of the invention

Eine erfindungsgemäße Einrichtung zum Empfang von Verkehrsmeldungen, kurz Verkehrsmeldungsempfänger, mit den Merkmalen des unabhängigen Patentanspruchs hat demgegenüber den Vorteil, dass unnötige Kosten in Verbindung mit dem Empfang von Verkehrsmeldungen vermieden werden. Ferner hat die erfindungsgemäße Einrichtung den Vorteil, dass bevorzugt solche Verkehrsmeldungen empfangen werden, die für einen jeweiligen Empfängerstandort relevant sind. Der Fachmann wird hierbei insbesondere auch zu schätzen wissen, dass der Nutzer des Verkehrsmeldungsempfängers nicht manuell zwischen den beiden Empfangseinrichtungen umschalten muss, was zum einen leicht vergessen werden kann, zum anderen aber auch eine Ablenkung eines Fahrzeugführers vom Verkehrsgeschehen bei Betrieb des Geräts in einem Kraftfahrzeug mit sich bringt, sondern dass diese Umschaltung automatisch erfolgt. Damit wird eine standortabhängig stets bestmögliche Versorgung mit Verkehrsmeldungen erreicht, zum anderen trägt die Erfindung durch verminderte Ablenkung des Fahrzeugführers zu einer Erhöhung der Verkehrssicherheit bei. Letzteres aber auch, da beispielsweise die Wahrscheinlichkeit, dass sich der Fahrzeugführer bei einer Auslandsfahrt unvermittelt in einer nicht gemeldeten Verkehrsstauung wiederfindet, signifikant verringert wird.An inventive device for receiving traffic information, short traffic message receiver, with the features of the independent claim has the advantage that unnecessary costs in connection with the receipt of traffic reports are avoided. Furthermore, the device according to the invention has the advantage that preferably such traffic messages are received which are relevant for a respective recipient location. The skilled person will appreciate in particular that the user of the traffic message receiver does not have to manually switch between the two receiving devices, which can be easily forgotten on the one hand, but also a distraction of a driver from the traffic during operation of the device in a motor vehicle but that this switching takes place automatically. Thus, a location-dependent always best possible supply of traffic information is achieved, on the other hand contributes to the invention by reducing distraction of the driver to increase road safety. The latter, however, also because, for example, the likelihood that the driver suddenly finds himself traveling in an unregistered congestion during a trip abroad, is significantly reduced.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

So ist es von Vorteil, wenn die erste Empfangseinrichtung durch einen Rundfunkempfänger, die zweite Empfangseinrichtung durch eine Mobilfunkeinrichtung gebildet ist. Dies ermöglicht in vorteilhafter Weise den Empfang von mittels Rundfunk übertragener Verkehrsinformationen anstelle vom Dienstanbieter abgefragter Informationen insbesondere beispielsweise bei Auslandsfahrten, wenn vom über eine Mobilfunkverbindung erreichbaren Dienstanbieter ohnehin keine für den ausländischen Standort relevanten Verkehrsmeldungen angeboten werden. So ist nämlich der Rundfunkempfänger in der Lage, im Rahmen eines Sendersuchlaufs über das Rundfunkfrequenzband selbsttätig diejenigen der empfangbaren Rundfunkstationen zu ermitteln, die Verkehrsmeldungen nach einem bestimmten Standard, beispielsweise dem TMC-Standard ausstrahlen, und eine solche Rundfunkstation einzustellen.Thus, it is advantageous if the first receiving device is formed by a radio receiver, the second receiving device by a mobile radio device. This advantageously makes it possible to receive traffic information transmitted by means of broadcasting instead of information requested by the service provider, in particular, for example when traveling abroad, if no traffic information relevant to the foreign location is offered anyway by the service provider that can be reached via a mobile radio connection. Namely, the broadcast receiver is capable of automatically detecting those of the receivable broadcast stations in the course of a station search via the broadcast frequency band, broadcasting the traffic reports according to a certain standard, for example the TMC standard, and to set such a broadcast station.

Eine vorteilhafte Ausführungsform der Erfindung richtet sich darauf, dass in der erfindungsgemäßen Empfangseinrichtung eine Tabelle vorgesehen ist, in der möglichen Standorten der Einrichtung Informationen zugeordnet sind, welche eine Umschaltung der Umschaltvorrichtung auf die erste oder die zweite Empfangseinrichtung bewirken.An advantageous embodiment of the invention is directed to the fact that in the receiving device according to the invention a table is provided in the possible Locations of the device are assigned information which cause a switching of the switching device to the first or the second receiving device.

Die Tabelle kann vorteilhafter Weise weiterhin dahingehend genutzt werden, dass in der Tabelle möglichen Standorten der Einrichtung ferner Adressinformationen zugeordnet sind, die eine Anwahl von Dienstanbietem mittels der Mobilfunkeinrichtung ermöglichen, und dass die Umschaltvorrichtung ferner dazu ausgebildet ist, in Abhängigkeit eines festgestellten Standorts eine Adressinformation aus der Tabelle auszuwählen und der Mobilfunkeinrichtung zuzuführen. Während es für einen RDS-Rundfunkempfänger anhand im RDS-Datensignal enthaltener Informationen möglich ist, festzustellen, ob von einer Rundfunkstation Verkehrsmeldungen, insbesondere solche nach dem TMC-Standard übertragen werden und der Rundfunkempfänger durch einen an sich bekannten Sendersuchlauf eine solche Rundfunkstation selbsttätig ermitteln kann, ist dies für über eine Mobilfunkverbindung erreichbare Dienstanbieter nicht ohne weiteres möglich. Hier schafft die vorliegende Weiterbildung der Erfindung Abhilfe, indem für mögliche Standorte Adressinformationen gespeichert sind, so dass in Abhängigkeit eines Standorts ein entsprechender Dienstanbieter angewählt werden kann.The table can be advantageously further used in that in the table possible locations of the device further address information is assigned, which allow a selection of service providers by means of the mobile device, and that the switching device is further adapted, depending on a detected location from an address information select the table and supply the mobile device. While it is possible for an RDS radio receiver based on information contained in the RDS data signal to determine whether from a broadcasting station traffic reports, in particular those are transmitted according to the TMC standard and the radio receiver by a known station search can detect such a broadcasting station automatically, this is not readily possible for service providers reachable over a cellular connection. Here, the present development of the invention provides a remedy by address information is stored for possible locations, so that depending on a location, a corresponding service provider can be selected.

Die in Figur 1 dargestellte erfindungsgemäße Einrichtung 1 zum Empfang von Verkehrsmeldungen, nachfolgend auch kurz Einrichtung 1, umfasst gemäß dem hier beschriebenen Ausführungsbeispiel eine erste Empfangseinrichtung 11 zum Empfang von Verkehrsmeldungen über einen ersten Übertragungsweg. Konkret handelt es sich dabei hier um einen Rundfunkempfänger mit einem Dekoder für nach dem eingangs erwähnten TMC-Standard übertragene Verkehrsmeldungen. Dieser ist in an sich bekannter Weise dazu ausgebildet, UKW-FM-Rundfunksignale mit überlagerten RDS-Informationen, die auch TMC-Verkehrsmeldungen enthalten, zu empfangen und zu dekodieren. Ein solcher Rundfunkempfänger ist beispielsweise in der DE 35 36 820 C2 beschrieben, wobei in Abweichung der dortigen Darstellung heute RDS-Gruppen des Typs 8A zur Übertragung von TMC-Verkehrsmeldungen von den Rundfunkanstalten genutzt werden.The inventive device 1 shown in Figure 1 for receiving traffic information, hereinafter also short device 1, according to the embodiment described here comprises a first receiving device 11 for receiving traffic information over a first transmission path. Specifically, this is a radio receiver with a decoder for traffic messages transmitted according to the TMC standard mentioned above. This is designed in a manner known per se to receive and decode FM-FM broadcast signals with superimposed RDS information, which also contain TMC traffic reports. Such a radio receiver is described, for example, in DE 35 36 820 C2, in which deviation from the local representation today RDS groups of the type 8A for the transmission of TMC traffic reports are used by the broadcasters.

Ferner weist die Einrichtung 1 eine zweite Empfangseinrichtung 12 zum Empfang von Verkehrsmeldungen über einen zweiten Übertragungsweg auf. Die zweite Empfangseinrichtung 12 ist durch eine Mobilfunkeinrichtung, etwa eine solche nach dem GSM- oder alternativ UMTS-Standard, gebildet, über die nach Maßgabe einer ihr zugeführten Telefonnummer ein Dienstanbieter angerufen werden kann, von dem über die bestehende Kommunikationsverbindung Verkehrsmeldungen, insbesondere solche, die betreffend die Codierung der Meldungen dem TMC-Standard genügen, an die abfragende Einrichtung 1 übertragen werden. Alternativ kann mittels der Mobilfunkeinrichtung 12 auch nach Maßgabe einer ihr zugeführten Internet-Adresse ein Internet-Dienstanbieter angewählt werden, von dem Verkehrsmeldungen über die bestehende Mobilfunkverbindung an die abfragende Einrichtung 1 geladen werden.Furthermore, the device 1 has a second receiving device 12 for receiving traffic reports via a second transmission path. The second receiving device 12 is formed by a mobile radio device, such as one according to the GSM or alternatively UMTS standard, via which a service provider can be called in accordance with a telephone number supplied to it, from the traffic over the existing communication link, in particular those concerning the coding of the messages comply with the TMC standard, are transmitted to the interrogator 1. Alternatively, by means of the mobile radio device 12, an Internet service provider can also be dialed in accordance with an Internet address supplied to it, from which traffic reports are loaded via the existing mobile radio connection to the interrogating device 1.

Es liegt im Bereich vorliegender Erfmdung, dass zum einen weitere Empfangseinrichtungen vorgesehen sein können, ferner kann es vorgesehen sein, dass auch anderweitige Übertragungswege zum Empfang von Verkehrsmeldungen genutzt werden. Konkret ist dabei ohne Beschränkung der Erfindung an alternative Rundfunkübertragungsverfahren, wie etwa DAB (digital audio broadcasting) oder DVB (digital video broadcasting) gedacht. Ferner können beispielsweise Satellitentelefon und alternative Mobilfunk-Übertragungsverfahren wie GPRS oder andere vorgesehen sein.It is within the scope of the present invention that, on the one hand, further receiving devices can be provided, and it can also be provided that other transmission paths are also used to receive traffic reports. In concrete terms, this does not restrict the invention to alternative radio transmission methods, such as DAB (Digital Audio Broadcasting) or DVB (Digital Video Broadcasting). Further, for example, satellite telephone and alternative mobile radio transmission methods such as GPRS or others may be provided.

Die erfindungsgemäße Verkehrsmeldungs-Empfangseinrichtung 1 umfasst weiterhin eine Ortungsvorrichtung 13 zur Bestimmung eines aktuellen Standorts der Einrichtung 1. Diese kann in vorteilhafter Weise, wiederum ohne Beschränkung der Erfmdung, auf einem an sich bekannten GPS-(global positioning system-) Empfänger basieren, der aus empfangenen Satellitensignalen einen aktuellen Standort der Einrichtung 1 bestimmt. Im Zusammenhang mit dem hier beschriebenen Ausführungsbeispiel der Erfindung genügt es dabei, wenn die Ortungsvorrichtung 13 eine Information darüber zur Verfügung stellt, in welchem Staat sich der Aufenthaltsort der Einrichtung 1 befindet. Dies kann beispielsweise durch einen Vergleich von mittels des GPS-Empfängers ermittelten Ortskoordinaten des aktuellen Standorts mit gespeicherten Grenzkoordinaten der Staaten realisiert werden. Alternative Ausführungsformen der Ortungsvorrichtung 13 liegen im Bereich der Erfindung.The traffic message receiving device 1 according to the invention further comprises a locating device 13 for determining a current location of the device 1. This can advantageously, in turn without limitation of the invention, based on a known GPS (global positioning system) receiver, the received satellite signals determines a current location of the device 1. In connection with the exemplary embodiment of the invention described here, it is sufficient if the location device 13 provides information about the state in which the location of the device 1 is located. This can be achieved, for example, by comparing location coordinates of the current location determined by the GPS receiver with stored boundary coordinates of the states. Alternative embodiments of the locating device 13 are within the scope of the invention.

Die erfindungsgemäße Verkehrsmeldungs-Empfangseinrichtung 1 umfasst weiter eine Umschalteinrichtung 14, mit der die Empfangseinrichtungen 11 und 12 verbunden sind. Die Umschaltvorrichtung 14 hat die Aufgabe, Verkehrsinformationen weiterverarbeitende Stufen 16, beispielsweise ein Fahrzeugnavigationssystem, das eine Fahrtroute von einem Stand- zu einem Zielort unter Berücksichtigung ggf. vorhandener Verkehrsmeldungen berechnet oder beispielsweise eine Fahrerinformationseinheit, die einem Fahrzeugführer empfangene Verkehrsinformationen optisch und/oder akustisch zur Kenntnis bringt, wie sie beispielsweise in der DE 35 36 820 C2 beschrieben ist, mit einer der beiden Empfangseinrichtungen 11 oder 12 nach Maßgabe ihr zugeführter Umschaltinformationen zu verbinden. Somit verarbeiten die weiterverarbeitenden Stufen 16 Verkehrsmeldungen, die entweder mittels des Rundfunkempfängers 11 oder der Mobilfunkeinrichtung 12 empfangen werden.The traffic message receiving device 1 according to the invention further comprises a switching device 14 to which the receiving devices 11 and 12 are connected. The switching device 14 has the task of traffic information processing stages 16, for example, a vehicle navigation system that calculates a route from a stationary to a destination taking into account any existing traffic reports or, for example, a driver information unit, the traffic information received visually and / or acoustically brings, as described for example in DE 35 36 820 C2, with one of the two receiving devices 11 or 12 in accordance with their switching information to connect. Thus, the processing stages 16 process traffic messages received by either the broadcast receiver 11 or the mobile radio device 12.

Die zur Ansteuerung der Umschaltvorrichtung 14 erforderlichen Umschaltinformationen sind bei dem hier beschriebenen bevorzugten Ausführungsbeispiel in einem Speicher 15 in tabellarischer Form abgelegt. Gemäß einer ersten einfachen Ausführungsform der Erfindung beschränken sich die in der Tabelle 15 abgelegten Umschaltinformationen auf eine Zuordnung einer der beiden Empfangsvorrichtungen 11 oder 12 zu einem Aufenthaltsstaat. So ist gemäß Figur 1, dort erste Zeile der Tabelle 15, beispielsweise dem Aufenthaltsstaat Deutschland DE (erste Spalte 151) die zweite Empfangsvorrichtung 12, also im vorliegenden Ausführungsbeispiel die Mobilfunkeinrichtung Tel (zweite Spalte 152) zugeordnet. Hingegen ist dem Aufenthaltsstaat Frankreich FR (erste Spalte 151) die erste Empfangsvorrichtung 11, also im vorliegenden Ausführungsbeispiel der Rundfunkempfänger RFE (zweite Spalte 152) zugeordnet. Gleiches gilt für die in der Tabelle exemplarisch weiterhin angegebenen potentiellen Aufenthaltsstaaten Belgien BE und Luxemburg LU.The switching information required for controlling the switching device 14 are stored in a memory 15 in tabular form in the preferred embodiment described here. According to a first simple embodiment of the invention, the switching information stored in the table 15 is limited to an assignment of one of the two receiving devices 11 or 12 to a host state. Thus, according to FIG. 1, the first line of the table 15 there, for example the state of residence Germany DE (first column 151), is associated with the second receiving device 12, that is to say the mobile radio device Tel (second column 152) in the present exemplary embodiment. By contrast, the host state France FR (first column 151) is assigned the first receiving device 11, that is to say the radio receiver RFE (second column 152) in the present exemplary embodiment. The same applies to the potential states of residence Belgium BE and Luxembourg LU, which are further exemplified in the table below.

Das Zusammenwirken von Ortungsvorrichtung 13, Umschaltvorrichtung 14 und Tabelle 15 stellt sich dabei so dar, dass bei Feststellung eines aktuellen Standorts der Einrichtung 1 mittels der Ortungsvorrichtung 13 die Umschaltvorrichtung 14 nach Maßgabe der diesem Standort in der Tabelle 15 zugeordneten Empfangsvorrichtung 11 oder 12 auf diese umschaltet. Dies bedeutet, dass den weiterverarbeitenden Stufen 16 nach Maßgabe der in der Tabelle 15 enthaltenen Umschaltinformationen entweder mittels des Rundfunkempfängers 11 empfangene Verkehrsmeldungen oder mittels der Mobilfunkeinrichtung 12 von dem angewählten Dienstanbieter abgerufene Verkehrsmeldungen zugeführt werden.The interaction of locating device 13, switching device 14 and Table 15 is such that upon detection of a current location of the device 1 by means of the locating device 13, the switching device 14 in accordance with this location in the table 15 associated receiving device 11 or 12 switches to this , This means that the further processing stages 16 are supplied in accordance with the switching information contained in the table 15 either by means of the radio receiver 11 received traffic reports or by the mobile radio device 12 retrieved by the selected service provider traffic reports.

Gemäß der in Figur 2 dargestellten vorteilhaften Weiterbildung der Erfindung beschränken sich die in der Tabelle 15 enthaltenen Umschaltinformationen nicht auf entweder die erste oder die zweite Empfangseinrichtung 11 oder 12. Dies würde nämlich bedeuten, dass die Einrichtung beispielsweise in allen Ländern außerhalb des Heimatlandes auf den Empfang von mittels Rundfunk übertragenen Verkehrsmeldungen festgelegt ist, da die Mobilfunkeinrichtung 12 fest auf die Telefonnummer des Dienstanbieters des Heimatlandes programmiert ist und auch sein muss, da die Telefonnummer eines für ein bestimmtes Land zuständigen Dienstanbieters nicht ohne weiteres feststellbar ist. Dies im Gegensatz etwa zum Rundfunkempfänger 11, der mittels eines Sendersuchlaufs über das Rundfunkfrequenzband und eines probehalber Empfangs der empfangbaren Rundfunkfrequenzen die Rundfunkstationen ermitteln kann, welche Verkehrsmeldungen nach dem gewünschten, hier TMC-, Standard übertragen.According to the advantageous development of the invention shown in FIG. 2, the switching information contained in the table 15 is not restricted to either the first or the second receiving device 11 or 12. This would mean that the device is receiving, for example, in all countries outside the home country is determined by broadcasting traffic reports, since the mobile device 12 is programmed to the telephone number of the service provider of the home country and must be, since the phone number of a responsible for a particular country service provider is not readily apparent. This in contrast to the radio receiver 11, for example, by means of a station search on the radio frequency band and a trial-and-error reception the receivable radio frequencies the broadcasters can determine which traffic reports according to the desired, here TMC, standard transmitted.

Gemäß der vorteilhaften Ausführungsform der Erfindung enthält die Tabelle daher zusätzlich zu dem Eintrag der auszuwählenden Empfangseinrichtung 11 oder 12 zumindest im Falle der Mobilfunkeinrichtung 12 vorzugsweise zusätzlich eine Adressinformation (dritte Spalte 153). Diese Adressinformation ist in der Regel eine Telefonnummer A1, unter der ein für den zugehörigen Standort zuständiger Dienstanbieter, hier eine deutscher Anbieter, zu erreichen ist.According to the advantageous embodiment of the invention, therefore, in addition to the entry of the receiving device 11 or 12 to be selected, the table preferably additionally contains address information (third column 153), at least in the case of the mobile radio device 12. As a rule, this address information is a telephone number A1 under which a service provider responsible for the associated location, here a German provider, can be reached.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist die Mobilfunkeinrichtung weiterhin zur Herstellung einer Internet-Verbindung eingerichtet. Für diesen Fall sind in der Tabelle 15 Internet-Adressinformationen für solche Dienstanbieter abgelegt, bei denen Verkehrsmeldungen über das Internet abgerufen werden können. Im vorliegenden Fall ist die bei Luxemburg LU der Fall, dem die Internetadressinformation A2 zugeordnet ist. Außerdem findet sich in der Tabelle in deren zweiter Spalte 152 hier der Eintrag iNet, woraus für die entsprechend anzusteuernde Mobilfunkeinrichtung 12 ersichtlich ist, dass es sich bei der anzuwählenden Adressinformation um eine Internetadresse handelt.According to a further advantageous embodiment of the invention, the mobile radio device is further set up for establishing an Internet connection. In this case, table 15 stores Internet address information for those service providers in which traffic messages can be retrieved via the Internet. In the present case, the case is Luxembourg LU, to which the Internet address information A2 is assigned. In addition, the entry iNet in the second column 152 can be found here in the table, from which it can be seen, for the mobile radio device 12 to be triggered, that the address information to be selected is an Internet address.

Da nicht davon auszugehen ist, dass in allen Ländern jeweils nur ein einziger Verkehrsmeldungsanbieter existiert, ist gemäß einer weiteren in Figur 3 dargestellten Fortbildung der Erfindung vorgesehen, dass in der Tabelle 15 die Adressinformationen aller oder zumindest mehrerer oder ausgewählter Dienstanbieter für die jeweiligen Aufenthaltsländer gespeichert sind. Ferner können Verkehrsmeldungen in ein- und demselben Land auch über verschiedene Übertragungswege, beispielsweise sowohl von mindestens einer Rundfunkstation, als auch von mindestens einem Dienstanbieter zur Verfügung gestellt werden. Für diesen Fall ist vorgesehen, dass den betroffenen Ländern im Speicher 15 die Umschaltinformationen für die verfügbaren Übertragungswege und gegebenenfalls zusätzlich die mehreren Adressinformationen zu einem jeden der Übertragungswege abgespeichert sind. Im Falle Deutschland DE sind beispielsweise zwei Telefonnummern A1 und A3 für zwei verschiedene Dienstanbieter angegeben. Für Luxemburg ist beispielweise eine Adressinformation A2 eines Internet-Dienstanbieters und zugehörig ein entsprechender Vermerk "iNet", dass es sich um eine Internetadresse handelt, sowie eine Rundfunkfrequenz F3 mit einem entsprechenden Hinweis auf die erste Empfangseinrichtung 11 in Gestalt des Rundfunkempfängers "RFE" abgespeichert.Since it can not be assumed that only a single traffic information provider exists in all countries, according to a further embodiment of the invention shown in FIG. 3, the address information of all or at least several or selected service providers for the respective countries of residence is stored in the table 15 , Furthermore, traffic reports in one and the same country can also be made available via different transmission paths, for example both from at least one radio station, and from at least one service provider. For this case, it is provided that the affected countries in the memory 15, the switching information for the available transmission paths and optionally additionally the multiple address information to each of the transmission paths are stored. In the case of Germany DE, for example, two telephone numbers A1 and A3 are given for two different service providers. For Luxembourg, for example, an address information A2 of an Internet service provider and a corresponding note "iNet" that it is an Internet address, as well as a broadcasting frequency F3 with a corresponding reference to the first receiving device 11 in the form of the radio receiver "RFE" stored.

Für den Fall, dass zu einem Aufenthaltsort bzw. -land mehrere Übertragungswege und/oder Dienstanbieter bzw. Verkehrsmeldungen ausstrahlende Rundfunkstationen existieren, ist vorgesehen, dass die Schaltvorrichtung 14 bevorzugt diejenige Empfangseinrichtung 11 oder 12 aktiviert, die in der Tabelle unter dem betroffenen Land an erster Stelle steht. Alternativ kann eine andere Priorisierung, beispielsweise mittels einer in der Tabelle eingetragenen entsprechenden Prioritätskennzeichnung vorgesehen sein.In the event that a plurality of transmission paths and / or service providers or traffic reports broadcasting radio stations exist for a location or country, it is provided that the switching device 14 preferably activates that receiving device 11 or 12, in the table under the affected country at first Job stands. Alternatively, another prioritization may be provided, for example by means of a corresponding priority identifier entered in the table.

Eine vorteilhafte und besonders benutzerfreundliche Weiterbildung der Erfindung sieht vor, dass die Einträge des Speichers 15 durch den Nutzer vorgenommen und verändert werden können. Hierzu verfügt die erfindungsgemäße Verkehrsmeldungsempfangseinrichtung 1 über eine Eingabeeinrichtung 17. Diese kann beispielsweise als Teil der Bedienoberfläche der weiterverarbeitenden Stufen 16 ausgebildet sein. Über die Eingabeeinrichtung 17 kann der Nutzer sowohl Rundfunkfrequenzen für TMC-Verkehrsmeldungen ausstrahlende Rundfunkstationen, als auch Adressinformationen löschen und eingeben. Auch kann der Nutzer eine Priorität für bestimmte Dienstanbieter bzw. Rundfunkstationen ebenso vorgeben oder verändern, wie für einen bestimmten Übertragungsweg.An advantageous and particularly user-friendly development of the invention provides that the entries of the memory 15 can be made and changed by the user. For this purpose, the traffic message receiving device 1 according to the invention has an input device 17. This can be formed, for example, as part of the user interface of the processing stages 16. Via the input device 17, the user can delete and input both broadcast frequencies for broadcast stations broadcasting TMC traffic reports, as well as address information. Also, the user may specify or change a priority for certain service providers or broadcasting stations as well as for a particular transmission path.

Die Funktionsweise der erfindungsgemäßen Verkehrsmeldungsempfangseinrichtung 1 wird nachfolgend anhand eines Beispiels erläutert, dem die Tabelleneinträge der Figur 3, im übrigen die Einrichtung 1 nach Figur 1 zugrunde liegt.The mode of operation of the traffic message receiving device 1 according to the invention will be explained below by means of an example, which is based on the table entries of FIG. 3 and, moreover, on the device 1 according to FIG.

Das Fahrzeug, in dem die erfindungsgemäße Einrichtung 1 betrieben wird, bewege sich im Gebiet der Bundesrepublik Deutschland. Die Ortungsvorrichtung 13, die vorzugsweise als Bestandteil eines Fahrzeugnavigationssystems ausgebildet ist, stellt folgerichtig durch Vergleich der aus den Satellitensignalen abgeleiteten Standortkoordinaten mit Grenzkoordinaten der Bundesrepublik Deutschland einen aktuellen Fahrzeugstandort innerhalb Deutschlands fest. Sofern die Einrichtung soeben eingeschaltet worden ist, liest die Schaltvorrichtung 14 die zu dem ermittelten Standort DE in der Tabelle vorhandenen Schaltinformationen, im vorliegenden Fall also "Tel" und "A1" aus. Folgerichtig aktiviert die Schalteinrichtung 14 die Mobilfunkeinrichtung 12 und führt dieser die Adressinformation, hier die Telefonnummer A1 zu. Die Mobilfunkeinrichtung 12 wählt daraufhin die Telefonnummer A1 an und fragt über die hergestellte Telefonverbindung Verkehrsmeldungen von dem angewählten Dienstanbieter ab. Da die Verkehrsmeldungen nicht statisch sind, sich also mit der Zeit verändern können, erfolgen in regelmäßigen Zeitabständen weitere Anrufe beim Dienstanbieter zwecks Abfrage aktualisierter Verkehrsmeldungen. Sofern Verkehrsmeldungen vorliegen, werden diese beispielsweise über eine Anzeige als Teil der weiterverarbeitenden Stufen 16 dem Fahrzeugführer zur Kenntnis gebracht. Ferner werden die durch die Verkehrsmeldungen repräsentierten Verkehrsstörungen in einer Navigationskomponente der weiterverarbeitenden Stufen 16 für eine Fahrtroutenberechnung berücksichtigt.The vehicle in which the device 1 according to the invention is operated, is moving in the territory of the Federal Republic of Germany. The location device 13, which is preferably formed as part of a vehicle navigation system, logically establishes a current vehicle location within Germany by comparing the derived from the satellite signals location coordinates with boundary coordinates of the Federal Republic of Germany. If the device has just been switched on, the switching device 14 reads the switching information available for the determined location DE in the table, in the present case thus "Tel" and "A1". Consequently, the switching device 14 activates the mobile radio device 12 and this leads to the address information, here the phone number A1. The mobile radio device 12 then dials the telephone number A1 and queries via the established telephone connection traffic messages from the selected service provider. Since the traffic reports are not static, so can change over time, made at regular intervals more calls to the service provider to query updated traffic reports. If there are traffic reports, they are brought to the attention of the driver, for example via an advertisement as part of the processing stages 16. Furthermore, the traffic disturbances represented by the traffic reports are taken into account in a navigation component of the further processing stages 16 for a route calculation.

An diesem Zustand ändert sich nichts, solange die Ortungsvorrichtung 13 feststellt, dass sich der Fahrzeugstandort innerhalb Deutschlands befindet. Stellt hingegen die Ortungsvorrichtung 13 anhand eines Vergleichs der ermittelten Standortkoordinaten mit den Grenzkoordinaten einen Grenzübertritt, beispielsweise nach Frankreich fest, liest die Umschaltvorrichtung 14 aus der Tabelle 15 die dem Eintrag Frankreich FR zugehörigen Umschaltinformationen aus. Im Fall der Figur 3 sind dies zumindest eine Information, dass in Frankreich auf Rundfunkempfang umzuschalten ist entsprechend dem Eintrag "RFE". Optional enthält die Tabelle 15 auch eine Rundfunkfrequenz F1, über die eine Verkehrsmeldungen übertragende Rundfunkstation zu empfangen ist. Die Frequenzeinträge sind nicht zwingend vorzusehen, da der Rundfunkempfänger 11 mittels eines Sendersuchlaufs selbsttätig eine Verkehrsmeldungen ausstrahlende Rundfunkstation ermitteln kann. Infolge der aus der Tabelle 15 ausgelesenen Informationen zum Eintrag Frankreich FR schaltet die Umschaltvorrichtung 14 auf die erste Empfangseinrichtung 11, also den Rundfunkempfänger um und stimmt diesen auf die in der Tabelle vorgefundene Rundfunkfrequenz F 1 ab. In der Folge werden von den weiterverarbeitenden Stufen 16 über Rundfunk empfangene Verkehrsmeldungen ausgewertet.Nothing changes in this state as long as the location device 13 determines that the vehicle location is within Germany. If, on the other hand, the locating device 13 detects a border crossing, for example to France, on the basis of a comparison of the determined location coordinates with the boundary coordinates, the switching device 14 reads from the table 15 the switching information associated with the entry France FR. In the case of Figure 3, this is at least one piece of information that in France is to switch to radio reception according to the entry "RFE". Optionally, the table 15 also includes a broadcasting frequency F1 via which a broadcasting station transmitting traffic information is to be received. The frequency entries are not necessarily provided because the radio receiver 11 by means of a station scan can automatically detect a broadcasting station broadcasting traffic information. As a result of the read out of the table 15 information on the entry FR France, the switching device 14 switches to the first receiving device 11, so the radio receiver and tunes it to the found in the table broadcast frequency F 1 from. As a result, received by the processing stages 16 via broadcast traffic information.
